I make it like this:
Add qeema to boiling water
And add salt, chilli to it
When the water has dried up
Add a little oil, and tomato puree ( if you want it overly saucy go for tomato paste)
Stir, bhoon
Add in masalas like methi, garama masla, anyting really
And when its nearly done...
I chop onions and peppers and leave it on a low heat
This way the qeema is cooked thoroughly, and onions and peppers are soft and chunky and visible
Add in spaghetti
And
Easy peasy
